UR 242 no audio in Cubase


Forgive my probable ignorance as theres probably something stupid im missing here.

Ive setup the driver on my daw pc,im playing my synth through balanced inputs 3/4,and i can hear my audio fine,until i activate cubase. I can hear the playback of my track through monitors,and i can see my audio registering on the transport panel,but not coming out of my speakers,any ideas welcom :blush:

Please help.
